A Voltage mapping of the left atrium showing a linear scar on the anterior wall around the base of the left atrial appendage (anterior–posterior view). Voltage and activation mapping were performed in atrial pacing from the proximal coronary sinus. Scar was defined as < 0.2 mV on voltage mapping. B Voltage mapping of the left atrium post-radiofrequency ablation (RFA) illustrating the Y-shaped line (ablation points) and failure conduction block over the line (white arrow) (anterior–posterior view). C Fluoroscopic anterior–posterior view showing the FARAWAVE catheter positioned at the anterior wall of the left atrium. D Voltage mapping of the left atrium post-pulsed field ablation (PFA) showing the five pairs of PFA applications (anterior–posterior view). E Activation mapping of the left atrium post-RFA and PFA (anterior–posterior view) showing the conduction block
